I also enjoy this game and spend most of the summer playing it. When we play we play on teams of two though. The best posts to use are pieces of PVC pipe. Also when we play, we use a point system that makes the game more competitive. One point is awarded if the opposing team fails to catch the frisbee, two points are awarded if the beer bottle hits the ground. If the bottle and the frisbee are both caught no points are awarded to the throwing team, but the beer must still be drank. Also, you must have a beer in your hand for the entire game, setting the beer down is not allowed.
